Be it known that I, GEORGE W. STINEBRING,

la citizen of the United States, residing at erence being had to theannexed drawings,

making a part of this specification, and to the figures of referencemarked thereon, in which- Figure l is a perspective view showing aportion of the sawmill frame or bedand illustrating the carriage feedand return mechanism properly assembled. Fig. 2 is a side viewillustrating the position of the friction-wheels, showing thefeed-wheels removed. Fig. 3 is a view showing a side elevation of thegrooved pulley, also showing the chain connected thereto, and a sideview of one of the cams designed to bring the train of friction-wheelsinto engagement to return the carrier. 4 is a longitudinal section. Fig.5 is a detached view of one of the-feed friction-wheel supports. Fig. 6is a top view showing a portion of the mill frame or bed. Fig. 7 is asectional view of the feed-friction-wheel cylinder, also a sectionalview of the feed friction- Wheel proper. Fig. 8 is a 'detached view ofone of the feed friction-wheel-thimble supports.

The present invention has relation to frictional gearing designed forsawmills and intended to feed the material being sawed to the saw and torun the carriage back after a cut has been made; and it consists in thedifferent parts and combination of parts hereinafter described, andparticularly pointed out in the claims.

Similar numerals of reference indicate corresponding partsin all thefigures of the drawings.

In the accompanying drawings, 1 represents the saw-shaft, which is ofordinary construction and is journaled to the sawmill frame or bed inthe usual manner and is provided with the power-pulley 2.

Upon the saw-shaft 1 is located the friction-pulley 3, whichfriction-pulley is located substantially as shown in the drawings and issecurely attached to the saw-shaft 1 in the Fig..

usual manner. Against the face or periphery of the friction-pulley 3 islocated the intermediate feed-wheel 4, said wheel being at all timesheld in close contact with the periphery of the friction-pulley 3.

Adjacent to the feed-wheel 4 is located the wheel 5, which wheel isprovided with the beveled face 6, and for the purpose of moving thewheel 5 out of engagement with the feed-wheel 4 during the time thecarriage is fed forward the feed-shaft 7 is journaled at one end to theswinging boxing or bearing 8,

f which boxing or bearing is provided with upward-extending arm 9, whicharm'is pivoted to one of the sills of the base or sawmill frame.

For the purpose of imparting rotary motion to the intermediate wheel 4and the wheel 5 and the fiat-faced peripheries of the intermediate wheel4 are in contact with the fiat face or periphery of the wheel 3.

To the cross-bar 10 is securely attached in any convenient andwell-known manner the bracket-bearing 1l, which bracket-bearing isformed of a sufficient length to properlyhold the rotatable head 12,which rotatable head is eccentrically mounted upon the shaft 13 and uponwhich shaft is securely mounted the beveled friction-wheel 14, whichbeveled friction-wheel imparts rotary motion to the wheel 5 as it comesin contact with the beveled face 6, formed upon the 'side of said wheel.

For the purpose of imparting rotary motion to the shaft 1 3 and thebeveled friction-wheel 14 the friction-wheel 15 is provided, whichfriction-wheel is slidably mounted upon the shaft 13 and is so locatedthat it will come in contact with the side face of the intermediatewheel 4 when it is desired to move the carriage forward to feedvertically to the saw.

It will be understood that when the wheel 3, which wheel is mounted uponthe sawshaft 1, is rotated it will impart rotary movement to the wheel4, which in turn imparts rotary movement to the wheel 15 when said wheelis brought in contact with the face of the wheel 4. The rotatable head12 is provided With the toothed segment 1G, which toothed segment mesheswith the toothed seglment 17, said segment 17 being securely attached tothe shaft 18, which shaft extends IOO rearward, and to its rear end ispivotally attached the operating-lever 19, said operatinglever beingextended upward a sufficient distance to give the desired amount ofleverage to operate the different parts, as hereinafter described.

The operating-lever 19 is extended downward below the shaft 18, and toits bottom or lower end is pivotally attached the rod 20, to which rodis` pivotally attached the connecting link or bar 21, which connectinglink or bar is connected to the arm 22, which arm is preferably formedintegral with the bau 23, said band 23 being mounted upon the hub 24 ofthe wheel 15, and for the purpose of holding the band 23 in properposition upon the hub 24 the plate 25 is securely connected to the hub23 by means of a set-screw 26 or its equivalent.

It will be understood that when the operating-lever 19 is moved so as toimpart a reciprocating motion to the rod 20 the frictionwheel 15 will bemoved to or from the center of the intermediate friction-wheel 4,thereby changing the speed of the friction-wheel 15, it being understoodthat when the frictionwheel is forced toward the periphery of thefriction-wheel 4 a rapid motion will be imparted and a slower motionimparted when it is brought toward the center of the intermediatefriction-Wheel 4, by which arrangement a rapid or slow motion isimparted to the feedshaft 7 by means of the wheel 5 and the beveledgear-wheel 14.

It will be understood that the friction-wheel 15 should be slidablymounted upon the shaft 13 and that said friction-wheel should be soconnected that it will impart a rotary movement to the shaft 13.

For the purpose of limiting the outward movement of the friction-wheel15 the shaft 13 should be provided with a stop-pin or its equivalent,such as 27. The intermediate friction-wheel 4 is mounted upon the shaft28, which shaft is held in the bearing 29, said bearing being held inproper alinement by moans of the yoke 30, which yoke is adjustable backandforth in the plate 3l, which plate is connected to one of the sillsof the sawmill-frame or its equivalent.

The yoke 30 extends rearward and is provided with a slot 32, throughwhich slot the clamping-bolts 33 are passed, said bolts also beingpassed through the sill of the sawmillframe.

The object and purpose of providing the adjustable yoke 30 is to adjustthe shaft 28 so as to bring the intermediate friction-Wheel 4 into truealinement between the Wheels 3 and 5.

For the purpose of holding the outer end of the bearing 29 the yoke 34is provided, which yoke is attached to a sill of the sawmill-frame. Thebearing 29 is provided with the screwthreaded cap 35, through whichscrew-threaded cap extends the screw-threaded bolt 36, said bolt beingso arranged that it will come against the end of the shaft 28, andthereby prevent any end movement of said shaft, this arrangement beingdesirable to bring to proper adjustment the intermediate friction- Wheel4 with reference tothe sliding frictionwheel 15.

The shaft 18 is held against end movement during the time the lever 19is moved to impart a reciprocating motion to the rod 20 by means ofsuitable collars 37, which collars are located upon opposite sides ofthe cross-bar 38 of the sawmill-frame propel'.

To the bracket-bearing 1l is attached or formed integral therewith thearm 39, which arm forms a support and bearing for the shaft 18.

For the purpose of forcing the friction.

wheel 5 against the intermediate frictionwheel 4 when it is desired tobring the carriage back after a cut has been made the swinging bearing 8is provided with the shaft 40, which shaft is journaled to the free endof the swinging bearing 8 and is provided with the cam-faced disk 41,which cam-faced disk rests against the cam-face disk 42.

The cam-face disk 41 is provided with the arm 43, to which arm isattached the chain 44, said chain being connected to the grooved pulley45, which grooved pulley or its equivalent is fixed to the shaft 18. Byimparting an auxiliary movement to the shaft 18 by means of the lever 19the grooved pulley 45 will kbe turned, and when turned in one directionthe faces of the cam-disks 41 and 42 will ride upon each other, therebyimparting a longitudinal movement to the rod 40 and crowd the swingingbearing 8 in the direction to force the wheel 5 against the intermediatewheel 4, this movement being brought about by alateral motion beingimparted to the operatinglever19. Whenalateralmovementisimparted to thelever 19 in one direction, the direction being the same that forces thewheel 5 against the intermediate wheel 4, the frictionwheel 15 and thebeveled friction-wheel 14 will be moved away from the beveled face 6 ofthe wheel 5 and the face of the intermediate friction-wheel 4, thismovement being brought about by means of the toothed segments 16 and 17,which segments act to impart a rocking movement to the rotatable head12, and by rotating said head the shaft 13 is moved to or from thewheels 4 and 5, this being accomplished by journaling said shafteccentrically to the rotatable head 12.

After the carriage has been run back for a new cut the operating-lever19 is so manipulated that the friction-wheels 15 and 14 will be broughtagainst the contact-faces of said wheels, and at the same time the Wheel5 will be released from contact with the intermediate friction-wheel 4.

It will be understood that the cam-disk 42 should remain at rest at alltimes, so that as the cam-disk 41 is rotated it will move the rod 40endwise, and for the purpose of accomplishing this object the disk 42should be IOO IIO

loosely mounted upon the rod 40 and held against end movement in anywell-known manner.

For the purpose of at all times holding the 5 inclined faces of thecam-disks 4l and 42 together a spring, such as 47, is provided, saidspring being interposed between the disk 41 and-a suitable flange 48,which ange is secured to the proper sill of the sawmill frame A 1o orbed.

y 2o through the cap 35 is to provide suitable adjustment from time totime between the faces of the intermediate friction-wheel 6 and thefriction-Wheel 15.

It will be understood that rotating the z 5 screw-threaded bolt 36 willchange the position of the axle 28, which in turn moves the intermediatefriction-Wheel 4 laterally. This adjustment is of course limited and isonly intended to compensate for the wearing away 3o of the surfaces ofthe intermediate wheel 4 and the friction-wheel 16.

It will be understood that the shaft 7 is to be provided with theordinary pinion, which meshes with the common rack-bar employed toimpart movement to the driving-carriage; but as these parts are old andcommon they are not illustrated, as they form no particular part of thepresent invention except that they are necessary elements in thecomplete Work- 4o ing of a sawmill.
